The `clippy::perf` lint group is fairly useful for catching bad practices that might hurt performance marginally. This PR fixes most of them except `clippy::large_enum_variant`, which doesn't feel right at this moment and need more researches. Anyway, overall this PR should be good.

The
clippy::perflint group is fairly useful for catching bad practices that might hurt performance marginally.This PR fixes most of them except
clippy::large_enum_variant, which doesn't feel right at this moment and need more researches. And that is why I didn't enable the lint group.How to test and review this PR?
